A blonde girl comes rushing home to her mum and says: "Mummy mummy!
Today at school everyone could only count to 3 but I can count to 5.
Look - 1, 2, 3, 4, 5. Does that mean I am special mummy?"

"Yes dear it does."

The next day the blonde girl comes running in again and says: "Mummy
mummy! Today at school everyone could only say the alphabet from A to C
but I can go until E. Look - A, B, C, D, E. Does that mean I am special
mummy?"

"Yes dear it does."

The next day the blonde girl comes rushing home and says "Mummy mummy!
Today at school we were getting changed for physical excercises and all
the other girls had really flat chests but I had these ...!" She opens
her blouse and reveals a humungous pair of DD breasts. "Is it because I
am special mummy?"

"No dear it's because you are 25."
